DETAILED DESCRIPTION

FIG. 1 shows a top schematic diagram of an antenna box module according to an embodiment of the present disclosure, wherein an antenna box is joined with an external connection wire module. Referring to FIG. 1, an antenna box module 200 of this embodiment may include an antenna box 210 and an external connection wire module 220. The antenna box 210 may include a housing 212 and a circuit board 214 disposed in the housing 212. The circuit board 214 may have multiple antennas 214 a. Each of the antennas 214 a is adapted to receive and/or transmit multiple wireless signals based on one of multiple wireless communication standards. In some implementations, these antennas 214 a are in different types from one another; for example, these antennas 214 a may have respective corresponding structures based on these different wireless communication standards. These wireless communication standards may include, without limitation, the Wi-Fi wireless communication standard, Bluetooth wireless communication standard, GPS wireless communication standard, 2G wireless communication standard, 3G wireless communication standard, 4G wireless communication standard, 5G wireless communication standard and/or WiMAX wireless communication standard.

Furthermore, the external connection wire module 220 may include a water-resistant element 228 and one or more external connection wires C. Each of the external connection wires C may include a first connector 222 and an external connection wire body 226. Moreover, the antenna box 210 may include one or more second connectors 224 disposed on the circuit board 214 and electrically connected to the circuit board 214. During use, one end of an external connection wire body 226 is connected to one first connector 222 to form one external connection wire C, such that the first connector 222 can be connected to, and be in electrical communication with, one second connector 224. The numbers of the first connectors 222, the external connection wire bodies 226 and the second connectors 224 are not specifically limited; however preferably, the numbers of the first connectors 222, the external connection wire bodies 226 and the second connectors 224 are equal. More details about the external connection wire C (e.g., a coaxial cable) and the second connector 224 are described in commonly owned U.S. patent application Ser. No. 17/141,998 filed Jan. 5, 2021 and entitled “Antenna Box Module, Connector Module and Coaxial Cable”, the contents of which being incorporated herein by reference in its entirety. However, the external connection wire C and the second connector 224 in the embodiments of the present disclosure are not limited to being the coaxial cable and the second connector described in U.S. patent application Ser. No. 17/141,998 referenced supra but may be any external connection wire and connector that transmits and/or receives signals.

These second connectors 224 are disposed on the circuit board 214 by means of, for example but not limited to, surface mount technology (SMT). By wires (not shown) on the circuit board 214, each of the second connectors 224 is electrically connected to one or more of these antennas 214 a. For example, one of these antennas 214 a can be electrically connected to one external connection wire body 226 through the coupling between one second connector 224 and one corresponding first connector 222, so as to transmit and/or receive signals (e.g., Wi-Fi signals) of the antenna 214 a to an external device (not shown). Another of the antennas 214 a can be electrically connected to another external connection wire body 226 through coupling between another second connector 224 and another corresponding first connector 222, so as to transmit and/or receive signals (e.g., 4G signals) of the another antenna 214 a to another external device (not shown). Yet another one of these antennas 214 a can be electrically connected to two or more external connection wire bodies 226 through coupling between two or more other second connectors 224 and two or more corresponding first connectors 222, so as to transmit and/or receive signals (e.g., 5G signals) of another antenna 214 a to another external device (not shown).

In some implementations, these antennas 214 a are all antennas in the antenna box 210; in other words, all the antennas (i.e., the antennas 214 a) in the antenna box 210 can be coupled to the outside jointly through these second connectors 224, without any other additionally provided connectors. Moreover, in some implementations, these antennas 214 a and these external connection wires C are in one-to-one correspondence; that is, the number of these antennas 214 a is equal to the number of these external connection wires C, and each of the external connection wires C is electrically connected to one unique one of these antennas 214 a.

The housing 212 has an opening 212 a which exposes these second connectors 224. The material of the housing 212 of the antenna box 210 may include a heat-resistant material such as, for example, plastic, and may be a mixture of PA resin and ABS resin, although other polymer types may be substituted in alternative implementations.

FIG. 2 shows an enlarged top schematic diagram of the water-resistant element and the external connection wires of the external connection wire module in FIG. 1 that have not yet been disposed on the housing. Referring to FIG. 2, the water-resistant element 228 includes a deformable body 228 a, a first plate 228 b and a second plate 228 c. The first plate 228 b may be disposed at and against a first side S1 of the deformable body 228 a (in a material such as, for example, rubber). The second plate 228 b may be disposed at and against a second side S2 of the deformable body 228 a. The first side S1 and the second side S2 may be opposite to each other. In such a variant, the water-resistant element 228 may further include an adjusting element 228 d penetrating through the first plate 228 b, the deformable body 228 a and the second plate 228 c. The adjusting element 228 d may include, for example, a screw bolt, and the first plate 228 b and the second plate 228 c respectively have a first screw hole H1 and a second screw hole H2 corresponding to the screw bolt, wherein the screw bolt can rotate relative to the first screw hole H1 or the second screw hole H2 to create a relative displacement between the first plate 228 b and the second plate 228 c. In some implementations, the relative displacement between the first plate 228 b and the second plate 228 c may be achieved through use of other devices other than the screw bolt. For example, a one-way ratcheting mechanism may allow the adjusting element 228 d to tighten with respect to the first plate 228 b thereby enabling the relative displacement without necessitating any type of special assembly tools (e.g., a screwdriver or allen key). In this implementation, the first plate 228 b may be held in a fixed position within the housing 212. A user may then press the second plate 228 c towards the first plate 228 b, causing the deformable body 228 a to deform in a direction that is generally orthogonal to the action. The one-way ratcheting mechanism may then engage such that the relative displacement between the first plate 228 b and the second plate 228 c prevents the second plate 228 c from returning to its prior form. Regardless of the implementation chosen, the relative displacement between the first plate 228 b and the second plate 228 c may be used to change the shape of the deformable body 228 a (to be described in detail below). Furthermore, each of the external connection wires C also penetrates through the first plate 228 b, the deformable body 228 a and the second plate 228 c. When the water-resistant element 228 is not yet disposed on the housing 212 as shown in FIG. 2, an interval T is kept between the first plate 228 b and the second plate 228 c, and the deformable body 228 a is not yet deformed and can be in a regular shape (e.g., a cylinder, cube, hexagonal cylinder, or other polygon-type shape) or have an irregular shape.

Referring to FIG. 1 and FIG. 2, when the antenna box module 220 is assembled, the water-resistant element 228 may be first disposed in the opening 212 a of the housing 212 of the antenna box 210, such that the deformable body 228 a is inserted in the opening 212 a and the first connector 222 of each external connection wire C is connected to the corresponding second connector 224. Next, the adjusting element 228 d is manipulated (e.g., by rotating the adjusting element 228 d in the form of a screw bolt) to apply pressure on the first plate 228 b and the second plate 228 c to decrease the interval T between the first plate 228 b and the second plate 228 c (the amount of decrease in the interval T is the relative displacement between the first plate 228 b and the second plate 228 c), further allowing the deformable body 228 a to deform in at least one direction perpendicular to the direction of interval T (i.e., perpendicular to the relative displacement) such that the deformable body 228 a closely fits the opening 212 a. Thus, the deformed deformable body 228 a closely fitting the opening 212 a is capable of preventing external dust or moisture from entering the inside of the housing 212 through the opening 212 a.

According to the description above, the deformable body 228 a of the water-resistant element 228 of this embodiment is deformable and thus closely fits the opening 212 a of the housing 212 by means of the adjustment of the adjusting element 228 d, so that the deformed deformable body 228 a closely fitting the opening 212 a is capable of preventing external dust or moisture from entering the inside of the housing 212 through the opening 212 a. Therefore, compared to the prior art, electronic components in the housing 212 are unlikely to be affected and hence damaged by external dust or moisture.

In some implementations, the opening 212 a of the housing 212 may be on one side surface 212 b of the housing 212. In another embodiment, the opening 212 a may also be located on a top surface 212 c of the housing 212 or a bottom surface (not shown) opposite to the top surface 212 c. When these second connectors 224 are located on the top surface 212 c or the bottom surface of the housing 212, these second connectors 224 can be electrically connected to the circuit board 214 by means of welding, insertion, soldering and/or other types of known connection methods.

In some implementations, one or more of these antennas 214 a in FIG. 1 may be replaced by other multiple electronic components having different functions. In other words, an electronic device including multiple electronic components (without an antenna function) having different functions can be used to substitute for the antenna box including antennas, wherein each of the electronic components is electrically connected to the corresponding one of these second connectors 224.

According to the description above, the embodiments of the present disclosure have one of the following or other advantages. The deformable body of the water-resistant element of the embodiments of the present disclosure is deformable and thus closely fits the opening of the housing by means of the adjustment of the adjusting element, so that the deformed deformable body closely fitting the opening is capable of preventing external dust or moisture from entering the inside of the housing through the opening. Therefore, compared to the prior art, the electronic components in the housing are unlikely to be affected and thus damaged by the external dust or moisture.
